' SOAP-DISSOLVER.

Specification of Letters Patent.

Application filed September 27, 1917. Serial 0. 193,508.

To all whom it may concern: 1

Be it known that I, JOHN L. Loom], a citizen of the United States, residing at Marion county, and State of Indiana, have invented and discovered cer tain new and useful Improvements in Soap- Dissolvers, of which the following is a specification.

My invention relates to soap dissolvers and its object is to provide an apparatus of this class capable of utilizing the ordinary open sheet metal tank now employed in laundries for dissolving chip soap and adapted to prevent the material from boiling over the open top of the tank, and at the same time obtaining a very rapid and complete dissolution of the soa With this object in view, my invention is embodied in preferable form in the apparatus hereinafter described and illustrated in the accompanying drawings in which Figure 1 is a vertical section, and Fig. 2 a horizontal section on the line 2-2 of Fig. 1.

Referring to the drawings, 1 is a tank of sheet metal which is open at the upper end and which is adapted to receive a body of soap chips and water, indicated at 2. Extending downward within this tank through the open end thereof is a suction and circulation pipe 3, connecting its lower end with a series of radially projecting branch pipes 4, extending toward the walls of the tank and having perforationsfi, formed in their longitudinal and end walls. These branch pipes rest upon the bottom of the tank and constitute supporting feet for the pipe 3.

steam conveying and, suctioncreating pipe 6 communicates with a suitable steam supply and extends down within the pipe 3 and at its lower part is provided with an upturned, open end 7, which is adapted to project a jet of steam upwardly in the pipe 3 and thus create a strong upward suction through the same which will serve to draw the soap chips and solution through the branch pipes and carry them upward through the pipe 3 to the opening in the elbow 8. This exit opening is above the tank and the solution and chips heated by the steam which mingle therewith in the pipe 3, are carried back into the tank and a constant circulation maintained. The steam serves to cook or heat the water and chips sufiiciently to facilitate the rapid melting of the same and at a lower temperature than is necessary in the ordinary practice.

Heretofore, it has been customary to heat the solution by stationary, non-circulating means of a high temperature, and constant attention is required to prevent the material from boiling or foaming over the top of the open tank, with consequent loss my invention, the constant circulation of the steam and solution not only serves to effectively agitate the same and, therefore, quickly effect the heating thereof, but also serves to permit the escape of the steam globules and prevent any accumulation of pressure such as would tend to force the material over the top of the tank.

The apertures in the branch pipes serve to cut the soap chips, as the same are drawn therethrough, and thus to so reduce them in size as to render them more quickly soluble.

The pipes may be supplied as a separate attachment for the ordinary dissolving tank now in use and merely applied thereto by setting the branch pipes in the tank and connecting the suction-creating steam pipe to a suitable source of steam.

Having thus described my invention, what I claim is:

1. A soap dissolving apparatus comprising an open tank adapted to receive a liquid and the soap to be dissolved, and a portable, removable attachment for heating and circulating the material and preventing boiling of the same over the top of the tank including a pipe extending into the tank and having .means to support the same on the bottom, said pipe being of comparatively restricted and uniform cross section throughout and perforated at its lower partto admit the material, and open at its upper end above the level of the material to discharge the same through the atmosphere back to the tank, and a steam conveying pipe leading downward through the first pipe and opening at its lower end into said first pipe to create a suction in the latter to induce the circulation of the said material.

2. A soap dissolving apparatus comprising a tank adapted to receive the soap to be dissolved and water, a pipe extending into the body of the material and constituting conveying means therefor said pipe being open at its upper end, and branch pipes extending radially from the first pipe and having perforations for the admission of the material, and means to introduce a suctioncreating and heating medium into said first Patented Feb. 25, 1919'.
